Zero Deadleg T-Valve, Manually Operated, Stainless Steel Block Ma-terial DN8-50

The Burkert Zero Deadleg T Valve system is

designed for control of ultra pure, sterile,

aggressive or abrasive fl uids. Enables

especially optimal sampling, draining or

diverting of critical process fl uids. The valve

body is machined from a single piece of block

material (monoblock – no weld seam).

The high quality diaphragms separate

hermetically critical fl uids from the actuator.

The manual actuator in PPS or stainless steel

can be sterilized.
